Philco 41-231 "Little Bullet"
#2

Resuming work on this chassis after returning home from Kutztown, I soon had all of the new capacitors and resistors installed.

The original speaker had some problems...

So...I used a speaker which was donated by a dead 41-221. The tears in the cone were easily repaired with fabric glue (great stuff for cones as it remains flexible after drying).

But what about the power switch?

With many thanks to Phorum member Sam, I soon had another 1941 six-button assembly. The switch did not work but was intact.

One of the main problems with these switches is the fact that the wires are spot welded to the switch contacts, and the welds fail over time.

I decided to try a rebuilding process with the unbroken switch housing from the assembly I acquired from Sam.

I used the contacts from the original 41-231 switch, cleaned them, and soldered new wires to them. The solder should never melt in normal operation.

Remembering the debacle of trying to tap threads into the mounting holes of the 41-231 switch assembly, this time I left the brass studs of the original rivets on the assembly I acquired from Sam. I had read on our sister Facebook group, Philco Radio Enthusiasts, where Mark Vaccaro used solid wire (leads from an old resistor) soldered to the old rivets to hold his switch in place...so I did the same thing. Only I added some of my strongest glue (Loctite Metal and Concrete Epoxy, the same glue which held my Tropic 41-745's grille together) along the sides to help hold the housing in place.
